SPECIFICATION forming part of Letters Patent No. 547,886, dated October15, 1895.

T at whom it may concern:

Be it known that I, ALFRED NICHOLAS, manufacturer, a subject of theQueen of Great Britain, residing on Water Street, in the city ofBirmingham, England, have invented new and useful Improvements in Bells,of which the following is a specification, and for which said inventionI have obtained Letters Patent of Great Britain, dated November 15,1894, No. 22,049.

My invention has relation to repeater-action bell mechanismcomprehending a repeatingstriker and means for communicating motionthereto;

Figure 1 of the accompanying drawings represents, partly in verticalsection and partly in elevation, a cycle-bell provided With'arepeating-striker and striker-operating mechanism constructed accordingto my invention. Flg. 2 represents a horizontal section of the bell uponthe dotted lines 0c 00, Fig. 1, thus showing the inter-gearing drivenand driving elements of the mechanism and the revoluble striker, whoseends are alternately made to strike and re'cede inward on each rotationof the casing, within which it is carried and wherein it stiffly slides.complete vertical section of the bell. Fig. 4 represents a similar viewas Fig. 3, but with the section taken at right angles upon the dottedline A of the said Fig. 3. Fig. 5 represents an elevation and top, side,and underneath plans of the striker-casing and its driving pinion. Fig.6 is a part section and a plan of the bolt-like striker separately. Fig.7 represents the arbor or upright spindle upon which the carrying-casingof the strikerrotates; Fig. 8 is a section of a different arrangement ofthe striker. Fig. 9 is a top plan view of the same. Fig. 10 is a planview of another different arrangement of striker.

The same letters of reference indicate corresponding parts in theseveral figures of the drawings.

Located within the interior of the hell on is a reciprocatingplunger-like striker I), carried by and working to and fro within arevoluble carrier or casing 0, having made fast to its under side apinion (1, through which pinion and the center ofthe casing and througha stop- Fig. 3 represents a hole I) in the striker an arbor or spindlee, carried by the base-plate j, upwardly passes and upon which thepinion and casing revolve when the said pinion is driven by its teethengaging with those of a double-toothed sectorf or a toothed sectorhaving upon the opposite part of the central stem or pillar g is acoiled spring h, with one end 72. made fast to the pillar and the otherend h taking around a stud f on the toothed sectorf, so that as the saidcombined sector and half-pinion is partly rotated through the teeth 2"of a toothed leversector turning about the pivot-pin i secured to thesaid base-platej as a center, the coils of the spring are wound up orcompressed, and its reaction automatically takes the strikeroperatingmechanism back to its normal position. The toothed sector there a thumblever or arm 4' extending through a gap 7" in the base-plate. Thus bypressing the said thumblever in'the direction of the arrow, Fig. 2, thetoothed sector 11 turns the toothed sector f through the medium of thehalf-pinion f, whereby the pinion d is rapidly rotated and with it therevoluble striker casing or carrier 0, which in itsturn carries with itthe plungerlike striker b, and, beinglonger than the casing, one orother of its ends is always projecting to a distance beyond one or otherof the casing ends, thereby coming within the range of the inside of thebell, so that as the projecting end is rapidly brought round and againstthe inside of the bell it strikes and rings the same, and is by theimpact impelled driven or shot back through the casing, causing theother end in its turn to extend alike unto the first-named end or to beready to again strike the bell when the said last named end is broughtround to its acting position. This is repeated continuously and tworings of the bell are made by every single rotation of the striker.

The hollow pillar or stem 9, which is car ried by the bell base-platej,has fitted within its upper part a rotating screw-box it with a milledhead 10 on its upper end and with the inside stem part receiving a likescrewed stalk m, having at its lower end a hook m over which the piercedand loose end a of a band-clip at, having its after end a made fast tothe base-platej, passes. The band-clip is drawn tightly around themember to which the bell is attached by turning the milled head whichdraws the screwed stalk m and with it the free end of the clip up to thestem 9; hence the connection.

Fig. 8 represents a section of a modification of the striker part of myimprovements, and Fig. 9 is a top side plan of the same. In this formthe striker 1) works within an opentopped casing 0 instead of a closedone and is made to move stiltly by a spring 13, located round thecentral stem 6, carried by the baseplatej and between the head e andawasher 6 coming upon the top side of the striker. a is the bell, d thepinion, andfthe driving-sector of it.

Fig. 10 represents a further modification of the striker part of myimprovements. In this arrangement the striker, which is now flat, is thesame in principle as the one already described, but the plungers are induplicate, so that to each rotation of the carrier four rings are giveninstead of two. a is the bell. Z) Zfiare the reciprocating strikers. cis the easing or carrier; cl, the pinion; e,the stem, passingthrough anaxial hole in carrier and pinion, and through slots or stop'holes in thestrikers. The stem has a coiled spring located around it and comingbetween the head thereof and a washer located upon the top side of theupper striker Z), which has a sinking about its middle for the lowerstriker to Work and be guided within. fis the sector driving the piniond, and j is the base-plate carrying the stem 6. \Vhen the double strikeris rotated, the ends are continuously driven in, as they impinge againstthe inside of the bell; hence four strikes and rings to each singlerotation.

Having fully described myinvention, what I desire to claim and secure byLetters Patent is- 1. In the strikers of repeater-action bell mechanism,the combination with arevoluble carrier driven by a pinion made fastwith it and turning upon a central axis, of a reciprocatin gdouble-ended striker, whose ends are alternately brought into and takenout of a striking position by being impelled rearward by impact onstriking and ringing, substantially as described and set forth.

2. In the strikers of repeater-action bell mechanism, the combinationwith a revoluble carrier driven by a pinion made fast with it andturning upon a central axis, of a pair of reciprocating double endedstrikers whose ends are alternately brought into and taken out of astriking position by being impelled rearward by impact on striking andringing, and a spring for stiffening the movement of said striker,substantially as described.

3. In the motion-transmitting mechanism for bells, the combination witha toothed leversector pivoted to the base plate, of a plate having twotoothed sectors revoluble about a central stem and with the teeth ofthelarger sector meshing with the teeth of the striker pinion and withthe teeth of the smaller sector meshing with the teeth of the said leverand driving sector, substantially as described and set forth.

4. In the motion-transmitting mechanism for bells, the combination witha lever sector turning about a pivot carried by the base plate, andmeshing with the teeth of one part of a double sector plate, the teethof whose other part engage with a striker pinion, of a coiled spring,whose ends engage with afixed part of the bell and the double sectorplate, respectively, substantially as and for the purpose described andset forth.

5. In the repeater-action mechanism of bells, the combination with alever sector turning about a pivot carried by the base plate and meshingwith theteeth of one part of a double sector plate, the teeth of whoseother part engage with the striker pinion, and a coiled spring havingone end secured to a fixed part of the bell and the other secured to thedouble sector plate, of a reciprocating double-ended striker boltcarried by a revoluble carrier and whose ends are alternately broughtinto and out of astriking position by striking the bell, substantiallyas described and set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

ALFRED NICHOLAS.
